[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present invention provides a vertical wire twisting mechanism for a protector casing machine, which has the following beneficial effects:

[0015] The vertical wire-twisting mechanism of this protector casing machine, by starting the first cylinder, the output shaft of the first cylinder drives the moving plate to move left and right through the fixed block. The moving plate moves towards the side of the casing wire. By starting the fourth cylinder, the output shaft of the fourth cylinder squeezes the screw inside the outer clamping frame on the back side. The limiting rod inside the outer clamping frame on the back side moves inside the limiting block until one side of the outer clamping frame on the back side fits against one side of the limiting block and cannot move further. Due to the reaction force of the fourth cylinder, the outer clamping frame on the front side moves forward, and the two outer clamping frames can move towards the separated sides. Due to the reaction force of the return spring, the casing wire can be clamped. Also, by starting the third cylinder and with the limiting groove provided, the output shaft of the third cylinder drives the second connecting block at the top of the limiting plate to move to the right or to the left. When the second connecting block at the top of the limiting plate drives the outer clamping frame to move to the right through the moving plate, the first connecting block at the bottom of the limiting plate can drive the inner clamping plate to move to the left through the movable plate. Thus, the two outer clamping frames and the inner clamping plate move in opposite directions, and the outer clamping frames and the inner clamping plate can perform repeated wire-twisting on the casing wire. By starting the second cylinder, the output shaft of the second cylinder drives the movable frame to move up and down, and repeated up-and-down wire-twisting on the casing wire can be performed, making the casing wire straighter and facilitating subsequent processing.

[0023] In summary, for the vertical wire-twisting mechanism of the protector casing machine, by starting the first cylinder 2, the output shaft of the first cylinder 2 drives the moving plate 5 to move left and right through the fixed block 4. The moving plate 5 moves towards the side of the casing wire. By starting the fourth cylinder 14, the output shaft of the fourth cylinder 14 squeezes the screw 17 inside the back outer clamping bracket 12. The limiting rod 7 inside the back outer clamping bracket 12 moves inside the limiting block 13 until one side of the back outer clamping bracket 12 fits with one side of the limiting block 13 and cannot move further. Due to the reaction force of the fourth cylinder 14, the front outer clamping bracket 12 moves forward, and the two outer clamping brackets 12 can move towards the separated sides. Due to the reaction force of the return spring 9, the casing wire can be clamped. Also, by starting the third cylinder 10 and with the limiting groove provided, the output shaft of the third cylinder 10 drives the second connecting block 22 at the top of the limiting plate 18 to move to the right or to the left. When the second connecting block 22 at the top of the limiting plate 18 drives the outer clamping bracket 12 to move to the right through the moving plate 23, the first connecting block 20 at the bottom of the limiting plate 18 can drive the inner clamping plate 15 to move to the left through the movable plate 19. Thus, the two outer clamping brackets 12 and the inner clamping plate 15 move in opposite directions, and the outer clamping brackets 12 and the inner clamping plate 15 can perform repeated wire-twisting on the casing wire. By starting the second cylinder 11, the output shaft of the second cylinder 11 drives the movable frame 8 to move up and down, and repeated wire-twisting on the casing wire can be performed up and down, making the casing wire straighter, which is beneficial for later processing, and solving the problem that the existing casing machine still does not have a wire-twisting mechanism. Since the casing wire outside the protector is not straight during production, it affects the product quality, so wire-twisting treatment is required.
